Valliant boiler not working

[bethheartchris]

Hi,Ijope someone can helpme.I have a Valiant Boiler and in the last 2 weeks a small leak has appeared under it.
Over the last few days Ive had to press the flame button to relight it to get hot water. The temp goes up then very rapidly goes back down. I cant even get hot water as of today and the heating just wont come on.
Sorry for bad wording!!
Any Ideas?

Oh it says F.64 on the front and did say F.24 if that helps anyone xx Thanx

Would help if you told us which Vaillant it is

 

[bethheartchris]

sorry, turbomax i think

 

[bethheartchris]

It just says F24 now, does no one have any idea what to do? x

Check your pump. I suspect it has stuck or needs changing.

Ok, thanks I'll tell my hubby to check that. x

it sounds like the diverter valve

 

[bethheartchris]

What does that mean?Is it expensive and difficult to repair?
